IMPROVEMENT IN MOLDS FOR BOOT AND SHOE SOLES.l

Specification forming part of Letters Patent No. 126,823, dated May 14,1872.

Specification describing an Improvement in Shoe-Soles, and in apparatusfor making the same, invented by WILLIAM J. B. MILLS, of the city ofPhiladelphia and State of Penn- Sylvania.

My invention'consists of a shoe-sole, having a bodyY shaped andcondensed and a border han ged by molding, as fully described hereatter, so as to be available Without the usual preliminary manipulationfor immediate appli-4 cation to a last, and for being attached to theupper. My invention further consists of certain devices, too fullyexplained hereafter to need preliminary description, for molding andanging the sole.

In the drawing, Figure l is a plan view of the mold for forming theshoe-sole; Fig. 2, a longitudinal section on the line a a, Fig. l 5 andFigs. 3, 4, and 5, transverse sections of the mold and sole on the linesb b, c c, and d d.

A is the base and B the platen of the mold, the former being placed onthe bed of any suitable press. The upper face of the base and under faceofthe platen are made to coincide with the desired shape of the sole. Ois a guard, adapted to and entirely surrounding the base, and lof suchinternal shape and dimensions that the edge of the sole will accuratelyfit into it. D is the follower, having a lian ge of such shape anddimensions as to eX- actly t but slide freely in the guard G.

ln using` the above-described devices the platen B and follower' D are,in the first instance, Withdrawn, and the crude sole is placed grainside downward on the base A, the edge of the sole fitting snugly withinthe guard C. The platen B is now forced down upon the sole so as toimpart the desired shape and density to the same, and the follower D isalso depressed, the flange, during its descent, 'orcin g the projectingborder of the sole downward into the space h, and thereby forming on theedge of the sole and entirely round the same, and at one operation, alip or flange, which renders the sole available for being applied to alast and stitched to the upper. By this molding of the sole not only isthe lower flange formed, but the body has the desired shape given to itby a pressure which imparts such density and stiffness to the leatherthat the usual rolling and hammering operations may be dispensed with.

I claiml. As anew article of manufacture and co1nmerce, a shoe-solehaving a body shaped and condensed, and a border flanged by molding, asset forth.

2. The combination of the guard C and follower D with the base A of themold.

3. The combination of the follower D with the base A and platen B.

4. The combination of the base A, platen B, guard C, and follower D. y
